Adjustable wrist band

The invention relates to an adjustable hinge for doors or windows, according to the preamble of claim 1.

Such adjustable wristbands are known, for example, from EP 0 460 620 B1 by the applicant. In the case of the articulated hinge described here, a plastic sleeve is inserted in the axially open, cylindrical mounting of the frame hinge part, in which the lower hinge pin section is rotatably held. The threaded plug can be screwed into an internal thread section aligned with the journal bearing and lifts the plastic sleeve mentioned to adjust the height of the hinge. So that there is no visible gap between the upper sliding flange of the plastic sleeve and the upper end face of the bearing in the frame hinge part when lifting this plastic sleeve, spacers can be attached to close this gap. The load of the weight held by the wing hinge part is transferred via its contact surfaces to the sliding flange of the plastic sleeve.

The object of the invention is to provide an articulated hinge in which an emergency storage and an emergency stop of the two hinge parts is guaranteed to one another without the hinge pin inserted into the two hinge parts during assembly or disassembly.

This object is achieved by the features of claim 1.

According to the invention, the wing hinge part has an axial extension on its underside, which projects into a recess above the mounting of the frame hinge part. This extension ensures an emergency storage and an emergency stop of the two band parts to each other during assembly or disassembly, as long as no hinge pin is inserted into the two band parts. It is preferably part of a plastic sleeve which is held firmly in a receptacle of the wing hinge part and in the absence of the hinge pin due to the weight of the wing down into the recess of the Frame hinge part is pressed. There, the lower end face of the axial extension is preferably supported on a radial collar of the upper metallic bearing sleeve. The sash hinge part can only be completely detached from the frame hinge part when the sash is moved upward against its weight until the axial extension no longer protrudes into the recess in the frame hinge part. This measure enables a single fitter to assemble a door provided with the corresponding hinge parts. First, the door leaf is preassembled in such a way that the axial extensions on the leaf hinge parts protrude into the recesses above the mounting of the frame hinge parts. Then the hinge pins are inserted in all hinges of the door, whereby the hinge parts are aligned with each other. Finally, the threaded plug is screwed into each frame hinge part, the ball in the threaded stopper lifting the lower end face of the hinge pin and moving the axial extension upward within the recess until it no longer comes into contact with the opposite surface of the frame hinge part.

This extension also significantly increases the security against burglary. With this hinge, it is not possible to separate the parts of the hinge by violently knocking out the hinge pin with the door closed. The wing hinge part is held in place by the axial extension which projects into the recess in the frame hinge part. Lifting to release the hinge parts is impossible with the sash closed.

In addition, the axial extension has an optical function, since it obscures the unobstructed view of the hinge pin when the wing hinge part is raised by the threaded plug. Finally, the axial extension can be provided with annular markings on its outer surface. When the wing hinge part is lifted by screwing in the threaded plug, the axial extension moves upward, so that the annular markings become increasingly visible with this movement. The axial adjustment position of the hinge can be determined on the basis of the markings.

Such hinges, which are used in particular for fastening front doors to front door frames, have, in addition to the height adjustment via the threaded plug, an adjusting device in the hinge part. - ->

which enables transverse adjustment in the sash level. Furthermore, a contact pressure adjustment, i.e. an adjustment of the distance of the sash level to the frame level can be realized with the sash closed.

The hinge according to the cited prior art can alternatively be provided with a single, lower journal bearing or with a lower and an upper journal bearing. In most applications, the use of a simple door hinge with a pin bearing below has prevailed.

The known door hinges generally have a permanent smoothness. In contrast, due to the rotatable hinge pin section held in the relatively soft plastic sleeve, it is difficult to ensure that the hinge pin is held vertically in the mounting of the frame hinge part. The quite soft plastic material tends to deform due to the one-sided load due to the weight of the wing attached to the wing hinge part and due to the repeated rotary movement of the hinge pin in the plastic sleeve, whereby the hinge pin axis is inclined to the axis of the sleeve. In addition, due to the axial support of the lower surface of the wing hinge on the sliding surface of the plastic sleeve, there are abrasions which cause the joint hinge to become dirty in the vicinity of the mutually movable contact surfaces.

It is therefore a further object of the present invention, while maintaining a high degree of smoothness in the relative movement of the hinge parts to one another, to increase the permanent and precise positioning of the hinge pin in the frame hinge part and to avoid visually disadvantageous abrasion on visible contact surfaces.

This object is achieved in that a) that at least one stationary, thin-walled and preferably metallic bearing sleeve with self-lubricating properties is arranged in the cylindrical bearing of the frame hinge part and b) that the hinge pin is supported in the axial direction directly on the threaded plug, one of the two each other supporting support surfaces has a spherical shape, and the support surface opposite the spherical support surface is concave and preferably has the shape of a spherical or conical recess.

The use of a stationary metallic bearing sleeve, in which the lower section of the hinge pin is guided, ensures that a defined bearing made of non-deformable material (metal) guides the hinge pin in the frame hinge part. Such a pin receptacle can be designed with very low tolerances for self-lubricating slide bearings known from mechanical engineering. A pivoting of the pin axis to the axis of the mounting of the frame hinge part is thus largely restricted.

Since the hinge pin is not supported by a height-adjustable sleeve in the hinge according to the invention, the axial supporting force must be introduced into the frame hinge part in another way. This is done by direct support on the threaded plug via the spherical and concave (spherical cap or conical) recess on the one hand. The concave formation of the support surface interacting with the ball has two reasons. First of all, with conventional metal material pairings, it is difficult to form a permanent point bearing which enables the weight held by the wing hinge part to be supported while the hinge pin is rotated at the same time. If the spherical support surface is supported only in a punctiform manner on a flat support surface, there is a risk that material particles will break out in the contact point after several thousand rotations of the hinge pin. Due to the breakouts in the contact surface, the corresponding contact surface is machined, whereby the smooth running of the bearing is considerably restricted in the shortest possible time. Such "seizing" of the support surfaces can theoretically be counteracted by using high-strength materials. As a result, however, the costs are increased disproportionately and the economy of the joint band is questioned. It is therefore proposed according to the invention to make the support surface opposite the spherical support surface concave, so that at least one circular contact between the support surfaces consists. With such a storage, no destruction of the support surfaces could be determined even with unusually high permanent loads.

In addition, the concave design of the opposite support surface has a centering effect. The spherical support surface is preferably realized by pressing a ball into the threaded plug. The concave portion of the lower end face of the hinge pin resting on this ball centers itself on this ball due to the weight carried by the wing hinge part. The possible pivoting of the axis of the hinge pin to the axis of the bearing in the frame hinge part (tilting of the hinge pin) is additionally reduced by this centering of the lower support surface of the hinge pin.

Individual features of the joint band according to the invention are known. For example, EP 0 065 215 A1 discloses a height-adjustable hinge in which the hinge pin of the wing hinge part is supported by a ball on a threaded plug that can be screwed into the frame hinge part. However, there is no concave support surface for centering the hinge pin here. Furthermore, for example, the German utility model G 83 18 296.9 discloses an articulated hinge with self-lubricating metal sleeves (sintered bearings), but here an extremely complex internal height adjustment and no simple height adjustment is realized by screwing plugs in the frame hinge part. The publications known from the prior art do not disclose an articulated hinge with a simple height adjustment device which enables the power and movement transmission from the hinge pin to the frame hinge part in such a reliable, smooth and play-free manner.

In addition, the support according to the invention of the weight absorbed by the wing hinge part within the hinge pin bearing of the frame hinge part avoids a visible contact and support surface on which traces of abrasion or movement could form, which would impair the visual appearance of the hinge band.

It would be possible to use a single, self-lubricating metallic bearing sleeve that protrudes through the entire cylindrical bearing of the frame hinge part. However, a short metallic bearing sleeve arranged at the top and bottom of the cylindrical bearing. As a result, costs can be reduced while the precision of the storage remains the same.

Preferably, the upper metallic bearing sleeve has a radially extending collar which rests on the peripheral surface around the upper opening of the cylindrical bearing. When the hinge is used correctly, there is no contact between this radial collar and the lower surface of the wing hinge part. However, if the threaded plug is completely unscrewed from the frame hinge part, the sash hinge part sinks until it rests on this upper radial collar of the self-lubricating metallic bearing sleeve. In this state, which is not intended for normal use of the joint band, the radial collar causes auxiliary lubrication of the surfaces of both band parts in contact.

The sintered bearings mentioned above can be used to form the self-lubricating bearing sleeves. However, there are preferably steel bearing sleeves that are coated with a polytetrafluoroethylene, e.g. sold under the brand TEFLON are coated.

Within the wing hinge part, the upper hinge pin section is preferably held in a plastic sleeve made of fiber-reinforced plastic. This plastic sleeve is inserted in a receptacle of the wing hinge part. It can be designed as an eccentric sleeve, whereby the distance between the plane of the closed wing and the plane of the frame is adjustable.

As already mentioned, the plastic sleeve has the axial extension. which extends below the receptacle of the wing hinge part and protrudes into a recess above the mounting of the frame hinge part. This extension ensures an emergency storage and an emergency stop of the two band parts to each other during assembly or disassembly, as long as no hinge pin is inserted into the two band parts. The plastic sleeve is held firmly in the receptacle of the sash hinge part and, in the absence of hinge pin, is pressed downward into the recess of the hinge hinge part due to the weight of the wing. There, the lower end face of its axial extension is preferably supported on the radial collar of the upper metallic between the bearing sleeve. The wing hinge part can only be completely detached from the frame hinge part when the sash is moved upward against its weight until the axial extension no longer protrudes into the recess in the frame hinge part. This measure enables a single fitter to assemble a door provided with the corresponding hinge parts. First, the door leaf is preassembled in such a way that the axial extensions of the plastic sleeves on the leaf hinge parts protrude into the recesses above the mounting of the frame hinge parts. Then the hinge pins are inserted in all hinges of the door, whereby the hinge parts are aligned with each other. Finally, the threaded plug is screwed into each frame hinge part, the ball in the threaded stopper lifting the lower end face of the hinge pin and moving the axial extension upward within the recess until it no longer comes into contact with the opposite surface of the frame hinge part.

The weight of the wing is preferably supported on the plastic sleeve via a radial shoulder.

The weight transfer from the plastic sleeve to the hinge pin can take place via its upper end face, on which a closed the upper end area of the plastic sleeve rests. In this case, however, the weight is introduced over almost the entire length of the plastic sleeve, which can lead to quite a large stretch. For this reason, the plastic sleeve can alternatively be provided with a stop which is axially supported on a complementary stop of the hinge pin. These cooperating stops are preferably formed by radial shoulders or flange surfaces of the components. The hinge pin can have, for example, a radial shoulder on which the lower end face of the plastic sleeve is supported.

As an alternative to the force transmission via the plastic sleeve, the force can be transmitted from the wing hinge part to the hinge pin via a metal ring. This metal ring is pushed onto the hinge pin. The metal ring is preferably positively fixed in the axial direction, in particular with the aid of a tongue and groove connection. One or more grooves are preferably formed in the hinge pin using the extrusion process. Complementary springs (radially inwardly projecting ribs) are formed on the inner surface of the metal ring, which engage in the grooves of the hinge pin and which are supported in the end regions of these grooves.

The metal ring preferably has an upper sleeve section which projects into the plastic sleeve in the wing hinge part, and the metal ring also extends axially at least partially below the receptacle of the wing hinge part so that it protrudes axially from the contour of the wing hinge part. This protruding section of the metal ring is partly in the assembled hinge within the recess above the mounting of the frame hinge so that it can form the above-described auxiliary storage when the hinge pin is removed.

Finally, the recess of the wing hinge part should be closed at the top with a cover plug in order to avoid open cavities which have an aesthetically disadvantageous effect and in which dirt can accumulate.

Further features and advantages of the invention emerge from the subclaims and from the following description of the drawings.

FIG. 15 shows a representation corresponding to FIG. 1 of a further embodiment of the joint band according to the invention.

The hinge shown in Fig. 1 consists of a frame hinge part 1, which can be fastened to a frame for a door or window by means of trunnions 2 and several screw holes 3. It also comprises a wing hinge part 4, which can be screwed to the wing of a door or window with a multi-part fastening plate 5. Frame hinge part 1 and wing hinge part 4 are connected to one another via the hinge pin 6, which in the present case is designed as a continuous pin held in both hinge parts 1, 4. An adjustment device is arranged within the mounting plate 5, which makes it possible to adjust the distance of the Vane to the axis of the hinge pin 6 in the transverse direction, ie in the illustration in Fig. 1 in the horizontal direction to vary. Such devices are known and need not be explained further here.

The hinge pin bearing according to the invention can be seen in particular in the enlarged representation of FIG. 2. Two self-lubricating bearing sleeves 8, 9 are arranged within a cylindrical bearing 7 of the frame hinge part 1. Both bearing sleeves 8.9 are made of steel and have a coating with polytetrafluoroethylene on the inside, which gives them self-lubricating properties. In these hard bearing sleeves 8.9, the hinge pin 6 is guided essentially without play. In order to transmit the axial support force from the wing hinge part 4 to the frame hinge part 1, the lower end face of the hinge pin 6 forms a support surface 10, which is supported on a spherical support surface 11 in a threaded plug 12, which is in a threaded section 13 in the frame hinge part below the Storage 7 is screwed. The spherical support surface 11 is formed by a steel ball pressed into the threaded plug 12. To screw the threaded plug 12, it has a socket wrench receptacle 14 for receiving a hexagon wrench.

The lower support surface 10 of the hinge pin 6 has a conical recess 32, which rests in a ring against the spherical support surface 11 of the threaded plug 12. As a result, the contact area is increased in comparison with a flat support surface at the hinge pin end and wear due to excessive pressure load does not occur. The resulting ring-shaped contact area, on the other hand, is sufficiently small to prevent excessive friction forces which could cause the threaded plug 12 to rotate when the hinge pin 6 is turned. In order to additionally secure the screw plug 12 from rotating, it can be glued within the threaded section 13 of the frame band part 1.

By comparing the representations of FIG. 1 and Fig. 3 it can be seen that screwing the threaded plug 12 into the threaded section 13 of the frame hinge part 1 causes the sash hinge part 4 to be adjusted in height with respect to the frame hinge part 1. The maximum adjustment path can can be freely selected due to the dimensioning of the components and is in the order of 5 mm for standard door hinges.

The hinge pin 6 is held in the wing hinge part 4 in a glass fiber reinforced plastic sleeve 15 which is inserted into a receptacle 16 of the wing hinge part 4. The upper opening of the receptacle 16 is closed with a cover plug 17.

The weight force is transferred from the wing hinge part 4 to the hinge pin 6 with the aid of a metal ring 18, which extends over a radial shoulder 19, in the present case a flange surface, of the plastic sleeve 15 against the peripheral surface around the lower opening of the receptacle 16 of the wing hinge part 4 supports. The metal ring 18 is in turn arranged in a stationary manner on the hinge pin 6. This connection can be seen in particular in FIGS. 5, 6 and 9. 5 and 6 show, the upper section of the hinge pin 6 has three grooves 20 evenly distributed over its circumference. The metal ring 18 has on its inside complementary springs 21, i.e. inwardly projecting ribs, which protrude into the grooves 20 of the hinge pin 6. A spring 21 of the metal ring 18 can be seen in the sectional view in FIG. 1. The spring 21 is supported in the end region 22 (see FIG. 5) of the groove in the axial direction, so that it prevents the hinge pin 6 from moving upward relative to the metal ring 18 and the wing band part 4 supporting the metal ring 18.

The plastic sleeve 15 is designed as an eccentric sleeve, which enables the distance between the sash level and the distance between the frame level to be adjusted when the door or window is closed. The plastic sleeve 15 also has rib-shaped springs 29 which protrude into the grooves 20 of the hinge pin 6. In this way, the hinge pin is rotatably held within the plastic sleeve 15 and thus within the receptacle 16 of the wing hinge part 4.

The metal ring 18 has an upper sleeve section 23 which projects into the plastic sleeve 15. So a firm connection between the

Plastic sleeve 15 and the metal ring 18 causes, even if none

Hinge pin 6 is inserted into the hinge. Furthermore, the lower one Section of the metal ring 18 an axial extension 24 of the wing hinge part 4. This axial extension 24 protrudes into a recess 25 above the cylindrical bearing 7 of the frame hinge part 1. When the threaded plug 12 is screwed down completely, the lower end face of this axial extension 24 bears against a radially extending collar 26 of the upper metallic bearing sleeve 8. This position is only achieved during assembly and disassembly of the hinge, so that here the PTFE-coated collar of the bearing sleeve 8 provides emergency lubrication of the lower end face of this axial extension 24. In the operating position (cf. FIG. 3), the support takes place solely via the spherical support surface 11 on the threaded plug 12.

As already mentioned, when installing a door or a window, the hinge without hinge pin 6 can be preliminarily preassembled by inserting the axial extension 24 into the recess 25. The hinge pins 6 can then be inserted into the two to four hinges arranged one below the other and raised by screwing in the threaded plugs 12. Conversely, simple disassembly is possible by unscrewing the threaded plugs 12 and knocking out the hinge pins 6 from the hinges and then lifting the door or window sash so far that the axial extensions 24 no longer fit into the recesses 25 above the cylindrical bearings 7 of the frame hinge parts protrude. This enables a single worker to independently assemble or dismantle heavy door or window sashes.

In Fig. 3 it can also be seen that the axial extension 24 formed by the metal ring 18 blocks the unobstructed view of the hinge pin 6 when the wing hinge part 4 is raised. In addition, annular markings 27 are arranged on the axial extension 24 formed by the metal ring 18, which are visible from the outside when the hinge pin 6 is raised. The position of the hinge pin can be read from these annular markings 27.

10 to 14 show an alternative embodiment of the joint band according to the invention. Here the weight force is transferred from the wing hinge part 4 via the lower section of the plastic sleeve 15 'to the hinge pin 6' transfer. For this purpose, the hinge pin 6 'is provided with a radial shoulder 28 which forms a stop for the plastic sleeve 15'. The lower end face 34 of the plastic sleeve 15 'lies on this shoulder and forms the complementary stop. The plastic sleeve 15 'itself has a radial shoulder 19' which is supported against the peripheral surface which surrounds the lower opening of the receptacle 16 in the wing hinge part 4. The lower section of the plastic sleeve 15 'thus essentially fulfills the same function as the metal ring 18 and forms an axial extension 24 which projects into the recess 25 above the bearing 7 for the hinge pin 6' in the frame hinge part 1 '. As with the metal ring 18 of the first embodiment, annular markings 27 are also provided on the lower, axial extension 24 on the plastic sleeve 15 '.

As in the previously described embodiment, grooves 20 'are arranged in the hinge pin 6', which are arranged opposite one another here and interact with axially extending ribs 29 'on the inner surface of the plastic sleeve 15' in order to twist the hinge pin 6 'within the plastic sleeve 15 ' to avoid.

A last simplified embodiment of the invention is shown in FIG. 15. Here, the hinge pin 6 "is supported via its upper end face 30 against an upper closed area 31 of the plastic sleeve 15". As can be seen in FIG. 15, a socket wrench receptacle 33 for receiving a hexagon wrench is used in the closed area 31 of the plastic sleeve 15 ", which serves to twist the plastic sleeve 15".
